This is a rerelease of a time-tested history of Yosemite National Park by one of its most respected historians. It portrays in terms of human experience the growth of a distinct and unique conception of land management and chronicles the thoughts and efforts of those who contributed to it. It tells of the obstacles overcome and of the pressures to break down the park concept and turn Yosemite to commercial and other ends that would deface its beauty and impair its significance. For these reasons, the audiobook is more than a history. It traces the evolution of an idea.
